Gorrcspondiinz; and like ports are referred to in the :tollowinp; description, and design noted in the several views of the ucco1npunyinp; drawings, hv similar reterence characters.

To illustrate the application of the invention, there is shown in the drawings c run ning gear of well ltnown construction and con'iprising; front wheels 1. rear wheels 2., trout axle P resu. :tnle 1-, reach. her front holster ti end retuon '1' 'l, lhe running sour slso :'0ll'|l 7].lSiQt-3 s. tongue i", :t cleric it secured to the tongue. hounds t) and i0 and strikes 11. secured to the bolsters.

in accordance with the present inimntio'in longitudinal hezuns 12 are secured as at 13 to the holsters 6 and 7. The beams 12 are secured to the holsters 6 and t adjacent the ends of the letter, end are held against relstivo inoveinonts by the securing; elements 13, closely related front cross bars 14: end it reur cross her it pair of vertical hers u re secured to end extend downwsrdlv troni each heeln 12 1 end are provided with vertieel slots ll" which open out through their front and rear sides and lower ends. These parts and a drug; yoke 1S pivot-ally connected as at 19 to the flrontaide 8, corn prise the noeens tor connecting the ground working unit to the running; Q6211. This ineuns involves at construction which not only permits it to be readily secured to the running gear shown in the drawings but to any oi? the many well lniown other running goers now on the nnurhet end in use.

The ground working unit c prises u trume 520 teeth E2], scrzipcr end weightosfl roller 'llho :trzune Ell (EOIHlJITl 1 side hers El i which are loosely re (rived. y the sl ll of the hers 1.6 end to the trout ends or which the drug yolrc ilfil is rmuioctcd us at 25. 'lhc cross he rs 5.56 (it the trmno ill) ere urrmigcd. in par" c and the cross hers ot each puir are relatively spoccd. "lhe spaces-i between the respective wire of cross bets 5% are closed at their lower sides h v boards 27 which are provided with openings 28 through which the teeth 21 project. A row of the teeth 21 is arranged between ouch pair of the cross hers 536. The number of teeth in the second row i roster than the nunilmr ot teeth in the lust or front row and the member oi teeth in the lust or rear lltt row is greater than the number of teeth in the second or intermediate row. Each row of the teeth 21 is secured to and between each pair of the cross bars 26 by clamp bars 29 which are in turn secured in place by bolts 30. The shanks of the teeth 21 are polygonal, and the clamp bars 29 are provided with polygonal recesses 31 for the re ception of the shanks. The frame 20 is reent'orced by cross rods 32. The rear cross bar 33 of the frame 20 is diagonally arranged. The scraper 22 which also extends diagonally of the frame 20. secured against the front side ot the cross bar 533 by a clamp bar 3t and bolts 35 Bearing hangers 36 are pivoted as at 37 to the inner sides of theside bars 24, and are provided near their tree ends with longitudinally extending slots 38 for the reception of the ends of the shaft 39 of the roller V The ground working unit is mounted for vertical adjustment, is held against lateral movement by the bars 16, and is caused to follow the movement of the running gear by the drag yoke 18. The teeth 21 and the scraper 22 project below the frame 20, and are adapted when in active position to be held in engagement with the ground under the Weight of the frame. As the bearing hangers 36 are pivotally connected to the frame 20, andas its shaft 39 is connected to the bearing hangers for movement in the direction of the length thereof, the roller 23 will not prevent the lowering of the frame when it is desired to effect the engagement of the teeth 21 and scraper 22 with the ground and will remain in contact with the ground when the frame is raised to move the teeth and scraper out of engagement with the ground. It will thus be apparent that the ground mayv be first harrowed and scraped and thereafter rolled.

The means by which the frame 20 may be raised and lowered comprises a shaft 40 extending longitudinallyof the running gear and journaled in bearings 41, drums 42 fixed to the shaft, cables L3 wound about the drums and connected as at ll to the frame bars 24, a. lever 45 pivoted to the shatt, a ratchet wheel 46 fixed to the shaft, and a pawl 47 pivoted to the lever andv engaging the ratchet wheel. The "frame 20 is adapted to b held in raised position by a pawl 48 engaging the ratchet wheel 46, and pivoted to a bracket 49 carried by and depending from one of the front cross bars 14. lVhen the frame 20 is in raised position the teeth 21 and scraper 22 will be out of engagement with the ground and the roller 28 in contact with the ground. When it is desired to bring about the enga 'ement of the teeth and scraper 22 with tie ground, the pawl 48 is moved o'utof engagement with the ratche wheelfi, whereupon the frame 20 carries and holds the'teeth and scraper in contact with the ground. The cables -.tpass over pulleys it) supported by the beams 12. T .10 machine may he pulled by a tractor which can be connected thereto through the medium of the clevis From the 'i' i'e; oin description, taken in connection with the armnnpairying drawings, it is believed that the advantages ot the con struction and operation ol' the machine will be readily apparent to thor-o skilled in thc art to which it appertaiiri.

It should be understood that the drawing 's are merely illustrative and do not pretend to give exact proportions. .l urthcrnlore,

the said drawings are illu.--:trativc of a preterred cmistruction, it being my expectation that various changes and modifications may be made without departing from the spirit and scope of the invention.

hat is claimed is z- 1. A machine of the character set forth, including a frame having side bars and pairs ot closely related cross bars, rows of teeth positioned between each pair of cross bars, clamp bars positioned between each pair ol cross bars and engaging the teeth, means socuring the clamp bars to the cross bars, and boards closing the lower sides of the spaces between the pairs of cross bars and having openings through which the teeth project.
